I’ve created this more than 5 years ago and from then I did very few modifications/addings to it.
The idea is simple – we have a test object that has methods that start with “test” word. I never pollute the global namespace with anything – including functions – so at the start individual/anonymous functions could not be added. Recently, I also added this feature.
It still remains with only one assert, $Test.ok – if its first parameter is false the test fails. I had in plan to implement others, but it was enough because it can simmulate all the others.
The example should explain how it should be used:
var MyTestObject = {
testMethod1: function ()
{
$Test.ok(true, "True assert");
},
testMethod2: function ()
{
//Multiple asserts - al must be true in order for the test to pass.
$Test.ok(true, "True assert");
$Test.ok(false, "False assert");
},
name: "MyName",
testName: function ()
{
this.changeName();
$Test.ok(this.name == "MyName", this.name + "!=MyName");
},
changeName: function ()
{
this.name = "ChangedName";
}
};
//adding a test object; all its methods that start with "test" will be executed
$Test.Add("My Test Object", MyTestObject);
//adding a test function and with the name "Func" for the test
$Test.Add("Func", function ()
{
$Test.ok(5 == 4, "5==4");
});
//adding a test function with no name for the test
$Test.Add(function ()
{
$Test.ok(5 == 5, "5==5");
});
//Runs all added functions and all functions that start with "test" from the added test objects
$Test.Run();
And this will produce the following output:
First are shown the anonymous functions (Test Object: Functions) and then the test methods from the test objects.
I know that it may appear rudimentary comparative to the actual unit testing frameworks like jsUnit, Screw.unit, js-test-driver, etc, but it did, and still does the job.
